Title (EN) POLYESTERS
(FR) POLYESTERS
Abstract:
(EN) The present invention provides a polyester which is the reaction product of reactants comprising: (A) an aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms; (B) an aromatic carboxylic acid and/or anhydride; and (C) a polyol. The invention also provides a coating composition comprising the polyester, a method of making the coating composition and the use of at least 2 wt% of a linear aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms as a replacement for at least 2 wt% of an aromatic carboxylic acid and/or anhydride in a polyester composition. This use may improve the UV resistance and/or stability of the polyester composition.
(FR) La présente invention concerne un polyester qui est le produit de réaction de réactifs comprenant : (A) un acide dicarboxylique aliphatique comprenant de 16 à 30 atomes de carbone ; (B) un acide carboxylique aromatique et/ou un anhydride ; et (C) un polyol. L'invention concerne également une composition de revêtement comprenant le polyester, un procédé de fabrication de la composition de revêtement et l'utilisation d'au moins 2 % en poids d'un acide dicarboxylique aliphatique linéaire comportant de 16 à 30 atomes de carbone en remplacement d'au moins 2 % en poids d'un acide carboxylique aromatique et/ou d'un anhydride dans une composition de polyester. Cette utilisation permet d'améliorer la résistance aux UV et/ou la stabilité de la composition de polyester.
